Description
Technical field
The present invention relates to a kind of portable natural gas drier, it belongs to the servicing unit of gas concentration detection apparatus, particularly unites the drier of use with gas-detecting device.
Background technology
Coal bed gas, shale gas are to compose to deposit a kind of in coal seam or the shale and be absorption, dissociate or the natural gas of dissolved state.In the conventional gas reservoir, generally be mainly free gas and solution gas, substantially there is not adsorbed gas, and in unconventional natural gas reservoirs such as coal seam and shale, adsorbed gas content is higher, adsorbed gas and free gas content are generally greater than 90% in coal seam and the shale, the size of absorption and free gas absorption air content is directly connected to the enrichment degree and the development technique of natural gas, particularly concerning unconventional natural gases such as coal bed gas, shale gas, adsorbed gas and free gas assay are the key factors of evaluating reservoir, reserve estimate and development and Design.Therefore, the test experiments of natural gas adsorbed gas and free gas content in the gassiness sample has been widely used in shale gas, the cbm exploration exploitation.When utilizing Routine Test Lab equipment to carry out the experiment of adsorbed gas and free gas content measuring, the single isolated vapor tight tank of gassiness coal petrography and shale sample need being packed into, vapor tight tank is placed in the water bath of constant temperature.The coal petrography or the shale that are placed in the hermetically sealed can begin to carry out the nature desorb, by wireway, plastic lined piping and a hermetically sealed can internal communication that terminates on the vapor tight tank, the other end stretches into U type buret upper opening, be placed with in the buret and dye coloured liquid, by U type connecting pipe principle the amount of gas is carried out reading and measure.This gas-detecting device all must with the supporting use of gas-drying apparatus.Existing air dryer mostly is cylindrical container, so be called dry letter again.Its end sealing, the other end is provided with lid, so that change drier.Be furnished with O-ring seal in the lid, can make the end sealing after screwing.The two ends of drying are " air cavity ", and the middle part is the drier storage area, have " orifice plate " to separate between storage area and the air cavity.The simple wall at air cavity place is provided with the turnover valve.During work, detected gas enters air cavity by pipeline by crossing valve, passes the drier storage area again, becomes dry gas, enters the air cavity of the other end of tube then, after outlet nozzle is delivered to gas detecting instrument.Use through on-the-spot, find that there is following defective in above-mentioned drying:
1, elongated being not easy to of cylindrical shell carried and collected;
2, the cover of the drying of big volume is difficult to screw, easily gas leakage.
Summary of the invention
The objective of the invention is: a kind of portable natural gas drier is provided, and compact conformation is convenient to move and carry, and the compact gas dryer of good airproof performance is fit to field condition and uses.
The technical solution used in the present invention is: the portable natural gas drier, mainly form by box base, inlet suction port, O-ring seal, orifice plate, box body, lid, up-hole plate, central intake pipe, drier and exhaust joint, box body is a cylindrical vessel, box body has the end, screw top at box body is connected with a lid, and a sealing gasket is arranged between lid and the box body.It is characterized in that: a cylindrical box base is arranged at the box body inner bottom part, the air chamber that a depression is arranged in the box base upper end, in the air chamber bottom centre bore is arranged, the top of centre bore is connected with a central intake pipe, centre bore lower end and horizontal air admission hole UNICOM, the outer wall that inlet suction port passes box body is fixed on the air admission hole of box base; The outer wall that has steam vent, exhaust joint to pass box body in the air chamber bottom of box base is fixed on the steam vent of box base; At the top of box base a circular orifice plate is arranged, between box base and orifice plate, O-ring seal is arranged; Central intake pipe passes the orifice plate centre bore; Top at orifice plate is filled with drier; A circular up-hole plate is arranged on the top of drier; Central intake pipe passes the up-hole plate centre bore.Detected gas enters central intake pipe from inlet suction port 2, upwards and from the central intake pipe upper end flows out; By after the drier drying, flow into the air chamber of box base through up-hole plate at the process orifice plate; Flow out from exhaust joint at last.
The upper surface of described orifice plate has the filtration air-permeable mattress; Described air-permeable mattress is made for the elastic polyurethane foam.
Described box body, lid, up-hole plate and orifice plate adopt lucite to make.
Beneficial effect of the present invention: portable natural gas drier of the present invention, be used for coal seam, shale air content test experiments, insert gas detecting system fast, to realize simultaneously screwing fast, compact conformation is easy to carry more and collects.Described lid adopts the bolt connection type type of attachment, is convenient to change drier and seals more reliable.Be particularly useful for the field condition experiment.
